Officials initially suspected that bath salts had played a role in the vicious attack on Ronald Poppo, which resulted in the man losing over half his face to cannibalism. A completed toxicology report, however, has confirmed that no bath salts or any other drug aside from marijuana was found in Rudy Eugene when was killed.

Eugene was shot off a Miami highway after he was discovered hovering over Ronald Poppo's body and presumably chewing off the man's face. It was later revealed by an initial toxicology report that Eugene had not actually consumed any of the man's flesh, as no remains of human flesh were found in Eugene's stomach.

Following the attack officials cracked down on bath salts, a street drug with growing popularity, because it was believed that the drugs had initiated Eugene's actions. Before assaulting Poppo, Eugene had taken off all of his clothes and proceeded to take off Poppo's- an action that could have been initiated by the drug that causes users to feel extremely hot and paranoid.

But now a completed toxicology report has revealed that the only drug that Eugene consumed before attacking Poppo was marijuana.

"The department's toxicology laboratory has identified the active components of marijuana," the medical examiner said in a statement. "The laboratory has tested for but not detected any other street drugs, alcohol or prescription drugs, or any adulterants found in street drugs."

The results may be hard for Eugene's family to swallow after they suspected that Eugene may have been a victim as well, who was drugged before he attacked Poppo.

"I knew my son. Rudy will never, never do something like that," Eugene's mother said during an ABC interview in June as she and Eugene's brother both denied that he might have suffered from a mental illness.
